To help us diagnose the issue efficiently, could you provide a stripped-down reproduction test case using the latest version? A live example would be fantastic! ✨

For your convenience, our documentation offers templates and guides on creating targeted examples: Support - Bug reproduction

Just a friendly reminder: clean, functional code with minimal dependencies is most helpful. Complex code can make it tougher to pinpoint the exact issue. Sometimes, simply going through the process of creating a minimal reproduction can even clarify the problem itself!

Thanks for your understanding! 🙇🏼

Hi @michelengelen
I've created simple demo. Take a look, still in the example scrolling not working.

I get it now... you are facing this since the container holding the grid does not have intrinsic dimensions. This necessity is clearly stated in the docs. If you give the modal the dimensions to calculate the render- and scrollerzones it will work as intended:

<Box
  bgcolor="background.paper"
  sx={{
    padding: '1rem',
    position: 'absolute',
    top: '50%',
    left: '50%',
    transform: 'translate(-50%, -50%)',
    width: '95%',
    height: '50vh',
  }}
>
  <DataGrid rows={rows} columns={columns} />
</Box>
